The phosphorylation level of a particular protein can be determined using a procedure based upon western immunoblotting, with Phos-tag™ reagent present in the SDS-PAGE gel. The Phos-tag™ reagent, supplied in the form of Phos-tag™ acrylamide (Wako Pure Chemical Industries, AAL-107), causes proteins to be resolved both on the basis of size and phosphorylation state. This means that phosphorylated and de-phosphorylated forms of the same protein can be distinguished.

We routinely select specific RNAi gene targets (400–600 bp) and primers using the RNAit software http://trypanofan.path.cam.ac.uk/software/RNAit.html. A single pair of PCR primers are designed that incorporate four selected restriction sites (not present in the RNAi target fragment) such that a single PCR product can be differentially digested and sequentially cloned. For example, using MCS1/2, the following primers could be used to clone antisense followed by sense fragments: Primer 1, XbaI–BamHI-5′
